Weight Converter

About the Weight

This weight and mass converter converts between kilograms, grams, pounds, ounces, tonnes, stones, and milligrams — every unit you are likely to encounter in cooking, fitness, shipping, and science. Converting weight is one of the most common measurement tasks because the metric and imperial worlds both weigh themselves differently. The fundamental conversions: 1 kilogram = 2.20462 pounds, the factor that drives all the kg-to-lbs and lbs-to-kg conversions used at the gym and on the scales. 1 pound = 16 ounces, and 1 ounce = 28.3495 grams. The stone, still used in the UK and Ireland for personal body weight, equals 14 pounds or 6.35 kilograms. A tonne (metric ton) is 1,000 kilograms, whereas a US short ton is 2,000 pounds — a common source of confusion in shipping and freight. The gym is where weight conversion matters most. Plates and barbell loads are often given in kilograms, body weight targets in pounds, and you need to move between them. In the kitchen, recipes switch between grams and ounces. For science and medicine, grams and milligrams are the standard. For people weighing on body scales, stones and pounds persist in the UK — you might weigh 12 stone 3 pounds, which is 77.6 kg. The converter handles all of these instantly in real time. Select the from and to units, type a value, and read the exact result. Whether you are setting up a barbell, converting a recipe, checking luggage weight, or figuring out shipping rates between kg and lbs, this converter does the heavy lifting for you.
